Disclosed herein is a silencer constituted by a casing, open at the lower extremity made to communicate with the source of compressed gases, and closed at the top by a cover, inside which are placed, from the bottom upwards, a first element, a filter and a second element which, jointly with the inner surface of the casing, define a first, a second and a third expansion chamber, respectively, for the compressed gases. The first expansion chamber communicates with the open extremity of the casing, the second contains the aforementioned filter, while the third, via a slit made in the cover, communicates with the outside. The first and second expansion chamber are inter-communicating because of through holes drilled in the first element, and likewise the second and third expansion chamber are inter-communicating because of through holes drilled in the second element.

Silencer for pneumatic equipment, comprising a casing, open at one extremity and closed at the other by means of a cover in which there is at least one slit, that can be locked in a removable fashion to the body of the compressed gas device with which it is used, in such a way that the open extremity communicates directly with a duct for the discharge of the gases in the said device, there being in the said casing, starting at the open extremity and going towards the cover, stably inserted and, at the same time, closely enshrouded peripherally by the inside surface of the casing, a first element, a filter, and a second element, of which the first element defines, in cooperation with the relevant part of the inside surface of the casing, a first expansion chamber for the compressed gases, as well as, in cooperation with the second element and with a portion of the inside surface of the casing delimited by the said elements, a second compressed gas expansion chamber that contains the said filter, while the second element defines, furthermore, in cooperation with the cover, a third expansion chamber for the compressed gases; both the said first and second elements being provided with a plurality of through holes to render the first chamber communicating with the second, and the second chamber communicating with the third, respectively, characterized in that said filter is constituted by a layer of porous material, said layer of porous material completely filling the aforementioned second expansion chamber and being constituted by at least two consecutive parts, namely a first part and a second part, that mate with the first and the second elements, respectively, the first part having a porosity greater than that of the second part.
